Great question posed by @Scott_Perry1 monitoring remote access VPN usage metrics.
here's link to latest/greatest R80.40 Logging and Monitoring Admin Guide
check the "note" on page // views and reports / Reports
Note - For Security Gateways R77.30 and lower, the ability to generate reports on Firewall and VPN activity is integrated into SmartConsole. To enable this functionality, activate the Firewall session event on the SmartEvent Policy tab. Select and enable Consolidated Sessions > Firewall Session.
The R77.30 reference does remind me of pain experienced by numerous customers when they upgraded SmartEvent/SmartReporter to the new NGSE (and subsequently R80.xx SmartEvent). Incorporating R77.30 SmartReporter features directly into R80.xx SmartEvent (with one database back-end) was good decision but customers did lose functionality (the big taboo).
R77.30 SmartReport included a great per-user report template for remote VPN usage. This report -- and the associated access or similar relevant data -- disappeared with NGSE and the incorporated reporting in R80.xx SmartEvent.
One customer in particular spent lots of cycles talking with R&D. The idea was to understand the R77.30 report and try to replicate in R80.xx SmartEvent. There was not a comprehensive "YES" to everything -- AND -- the various data points were available in various different places and metrics (if I recall correctly).
I don't feel the customer's issues were ever resolved to satisfaction but I do understand some improvements were made with subsequent releases.
However, I would repeat this "should be easier".
Please bring back the R77.30 SmartReport template for remote access VPN usage.
